A resin-made fuel inlet pipe that has a light weight, excellent impact resistance, and causes no fuel leakage includes at least one resin layer comprising a resin composition containing (A) a high-density polyethylene (HDPE) or a linear short-chain branched polyethylene; (B) a polyethylene polymerized with a metallocene-based catalyst; and (C) a carbon black. A weight mixing ratio ((A)/(B)) is in a range of from 10/90 to 90/10; a content of component (C) is in a range of from 0.1 to 5 parts by weight with respect to 100 parts by weight of a total of components (A) and (B); a tissue (Y) comprising component (B) is inserted between linear crystalline tissues (X) comprising component (A) to expand an interval between the tissues (X); and component (C) is dispersed in the tissue (Y).

Resin-made fuel inlet pipe, and method for producing same

A resin-made fuel inlet pipe having a light weight excellent impact resistance, and causing no fuel leakage, includes: a tubular inner layer; and an outer layer laminated on an outer peripheral surface thereof, in which: the inner layer is formed of a resin having fuel resistance; the outer layer is formed of a resin (A) having a tensile elongation at 8 m/s measured by a high-speed tensile test of 200% or more; and the inner layer and the outer layer are in a substantially non-adherent state.

A rotary valve () includes a valve body () formed with a chamber communication passage () for flowing a main fluid and a vent communication passage () for discharging the main fluid and a cylindrical valve member () rotatably held in the valve body () and formed with a main passage () for flowing the main fluid. The cylindrical valve member () is rotated to switch the connection of the main passage () between the chamber communication passage () and the vent communication passage (). The rotary switching valve () further includes a purge gas passage for passing purge gas in a clearance () between the valve body () and the cylindrical valve member (), the purge gas being supplied to the clearance () to prevent the main fluid from leaking out of the main passage ().

To provide a low-cost air-operated valve, an air-operated valve comprises a piston, a cylinder in which the piston is allowed to slide by operation air, and a valve section to be driven by sliding movement of the piston. The cylinder includes an outer member having a hollow portion and an inner member loaded in the hollow portion of the outer member to define a piston chamber in which the piston is allowed to slide.

Valve

A hand-operated valve with a locking mechanism is disclosed. This valve includes: a valve main body including a valve body, a valve seat, and a screw mechanism which is actuated to bring the valve body into contact/noncontact with the valve seat; a locking mechanism for preventing actuation of the screw mechanism during a time when the valve body is in contact with the valve seat to close the valve; an operating member connected to the valve main body, for actuating the screw mechanism for contact/noncontact operation of the valve body with respect to the valve seat to thereby close/open the valve; and a play providing mechanism interposed in a connection between the operating member and the valve main body, for preventing the actuation of the screw mechanism during a predetermined stage of operation of the operating member.
